1804694 - Use sparse git checkouts instead of a full clone

Status: NEW

(Testing :: Raptor, task, P2)

Description

[Greg Mierzwinski [:sparky]]

This bug is for performing sparse checkouts instead of a full clone for the tests. This will help dealing with larger repositories like the perf-automation one (which is 500Mb for the full clone).

I've written some code for this that works locally but it requires git 2.30+:

    def _sparse_clone(self, benchmark_repository, dest):
        subprocess.check_call(
            ["git", "clone", "--depth", "1", "--filter", "blob:none", "--sparse", benchmark_repository, dest]
        )
        subprocess.check_call(
            ["git", "sparse-checkout", "set", self.test.get("repository_path", "benchmarks")],
            cwd=dest
        )

The dependency is now resolved, is there anything else stopping us from moving forward with this optimisation?

Nope, we can prioritize this now.
